ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 783,947, dated February28, 1905.

Application filed June 14,1904. Serial No. 212,539.

To all who/r1. it may concern;

Be it known that 1, WILLIAM A. Germans, a citizen of the United States,residing at Collinsville, in the county of (irrayson and State of Texas,have invented certain new and useful Improvements in Acetylene ti'rasGenerators, of which the following is a specification.

The object of my invention is to provide a novel construction ofgas-generating machine which is composed primarily of a single mainreceptacle having a generating-chamber, carbid-holder, valve mechanismcontrolling the feed of the carbid to the generatirig-chamber, and agas-bell mounted upon the generator and connected with the valvemechanism aforesaid for operation thereof. The gas-space of thegenerating-chamber communicates with the gas-space of the gas-belldirectly, and because of the arrangement of the generator with referenceto the carbid-holder and bell the whole machine is made in very compactform.

The invention obviates the necessity of use of a generator and aseparate gasometer having numerous intermediate connections andgas-controlling means, thereby greatly cheapening the cost of thegenerator and increasing the general desirability of my structure.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand accompanying drawings.

While the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which- Figure1 is a vertical sectional view of a gas-generating machine embodying myinvention. Fig. 2 is a horizontal section on the line X X of Fig. 1.Fig. 3 is a horizontal section on the line Y Y of Fig. 1.

Correspomling and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Describing and designating the essential features of my inventionstructurally, my machine COIHPI'iSGS prii'icipally a generator 1,

which consists of a tank of suitable size governed chiefly by the amountof gas tobe produced by the machine, and the carbid-holder 2 is disposedat the upper portion of the generator. The generator 1 is designed toreceive water, within which the carbid is projected upon operation ofthe valve mechanism, and at the upper end of the generator-receptacle 1and sliu'rounding same, preferably, is located the gas-bell 3. The upperend of the generator 1 is reduced diametrically, and the reducedportion, which is indicated at 1", is received within the gas-bell 3, asclearly shown in Fig. 1. The upper end of the generator 1 is open, sothat the gas-space within the generator d irectly communicates with thegas-space of the hell 3, and the decrease and increase of thegaspressure within the generator will induce the necessary responsiveaction of the bell and op eration of the valve mechanism operated bysaid bell and by which the feed of carbid is regulated.

The carbidreceptacle 2 is of a suitable form for the purpose of theinvention, being somewhat cone-shaped at its lower end, as shown at 2,so that the carbid will :feed regularly and to prevent formation of deadspace within which the carbid might accumulate. Within the holder 2 isdisposed a casingt, closed at its upper end, and the valve 5 operateswithin the casing, being movable toward and from a seat 6 adjacent theopening 7 in the lower end of the carhid-holder 2. The valve isprotected by the cesing 4 from the carbid within the holder, said casingbeing disposed slightly above the lower end of the holder and supportedby suitable supports or wings 8,-

resting upon the portion 2 of the carbid-receptacle. The valve 5 isoperated directly by a rod 9, connected at its lower end to one end of apivoted lever 10, and. a second valverod 11 connects the other end ofthe lever 10 with the gas-bell 3. The upper end of the rod 11 is thepart thereof which is actuated by the hell 3, said rod 11 passingthrough a guide member, (indicated at 12.) The valve-rod 11. is guidedin its vertical movement by a guide-tube 13, and in order that thevertical movement of the gas-bell 3 may be uniform and to preventbinding of the bell in such movement a guidebar 14 is projected upwardlyfrom the generator at a point approximately opposite to that part of thegenerator adjacent which the rod 11 moves, said guide-bar let passingthrough a second guide member 15, extending laterally from the upperportion of the bell 3.

of the genportion in Upon the reduced upper end 1 erator 1 andsurrounding said spaced relation thereto is a shell 16, which forms anannular chamber around the generator, said chamber receiving a liquid toform the necessary liquid seal between the hell 3 and the generator. Aguide-tube 13 is attached to the outer portion of the shell, abovedescribed. The location of the shell 16 is such that the compactness ofthe arrangement of the parts of the machine is promoted.

The lever 10 within the generator 1 is pivoted to a horizontalservice-pipe 17, which is located transversely of the lower portion ofthe generator, said service-pipe being provided with a vertical support18, to which the lever 10 is directly fulcrumed. The servicepipe 17extends out of the generator to any suitable point. The verticalsupply-pipe 19 extends upwardly from the portion of the service-pipe 17disposed within the generator, the upper end of the said pipe 19 beingprojected into the gas-space within the generator.

Suitable caps 20 and 21 are provided upon the bell 3 and thecarbid-holder 2, respectively, and these caps may be removed or replacedfor obvious purposes. Lugs 22 or other suitable means may be projectedfrom the upper portion of the carbid-holder to support same in the upperportion of the generator.

The vertical stand-pipe 27 is shown in dotted lines in Fig. 1, and thispipe may be of any suitable form, being preferably adapted to turn downin order to draw off the residuum which may have collected in the bottomof the generator. The lower end of the standpipe 27 is connected withthe lower end of the generator by any suitable coupling. Theservice-pipe 17 is provided in its length with a drier 28, whichcommonly used for this purpose, and a dri receptacle 29 is connectedwith the lower end of the drier 28.

In order to set up and agitate the residuum in the generator preparatoryto drawing 05 of the same, an agitating-arm 23 is disposed horizontallyin the lower portion of the generator and said arm is actuated bymeansof a vertical rod 24, projecting upwardly therefrom. The vertical rod 2passes through the guide-tube l3 and is with a handle 25.

A cotter-pin 26 is provided adjacent the upper end of the valve-rod l1,and this pin is provided at its upper end may be of any suitable type Iadapted to be engaged by the adjacent guide member 12 in the downwardmovement of the bell 3. The engagement of the member 12 with thecotter-pin actuates the rod 11 so as to open the valve 5 to therebyadmit of passage of the carbid from the holder 2 into the generator 1.

In its practical operation the variation in pressure of the gas withinthe generator 1 'etfects the operation of the gas-bell 3, reduction ofsuch pressure causing the said bell to lower, and this movement effectsengagement of the guide member 12 with the cotter-pin 26, thus causingthe valve 5 to move away from its seat. Carbid is thus fed into thegenerator-chamber and the increase of pres: sure in said generatorraises the gas-bell and the member 12 moves out of engagement with thecotter-pin, thereby shutting off the flow of carbid due to seating ofthe valve5.

Having thus described the invention, what is claimed as new is- In anacetylene-gas generator, the combination of a generator having its upperportion reduced, a shell surrounding the upper portion of the generatorand forminga liquidchamber, a bell having its lower end received in theliquid-chamber aforesaid, a carbidholder mounted in the upper portion ofthe generator, a valve controlling the feed of carbid from said holder,a service-pipe disposed transversely in the lower portion of thegenerator, a vertical supply-pipe leading from the gas-space of thegenerator into the servicepipe, a lever pivoted to the horizontalservicepipe in the generator, a rod connecting one end of the lever withthe valve, a second rod connected at its lower end with the other end ofthe lever and having its upper end projected out of the generatoralongside of the gas-bell, a guidetube secured to the shell aforesaidand receiving the valve-rod adjacent the bell, a guide-bar projectedupwardly from the generator at the side opposite that upon which thelast-mentioned valve-rod is disposed, guide members projected laterallyfrom the upper portion of the bell and cooperating with the guide-barand last-mentioned valve-rod to direct the movement of the bell, and apin extended from the upper end portion of the lastmentioned valve-rodand adapted to be engaged by the adjacent guide member of the bell toeffect actuation of the valve.

In testimony whereof I afiiX my signature in presence of two witnesses.
